SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 277,026, dated May 8, 1883. Application led December 30, 1882. (No model.)

To all whom, it may concern:

Be it known that we, JOSEPH HALL and LOUls ST. ANDR, citizens of the United States, residing at Clear Lake, in the county of Polk and State of Wisconsin, have invented a new and useful Saw-Handle, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to saw-handles, and has for its object to provide a simple, inexpensive, and eicient handle that is adapted to be conveniently secured to or detached from the saw-blade with great facility.

In the drawings, Figure l is a perspective view of our improved saw-handle clamped in position on a saw-blade. Fig. 2 isa longitudinal sectional view through the handle and blade. Fig. 3 is a cross-section of the same.

' Referring to the drawings, A designates the blade of the saw, and B designates the removable handle. The latter comprises in its construction a pair of clamping-levers, C C', that are fulcrumed at opposite ends of a connecting cross-piece, D, and have iuturned bifurcated clamping ends E, as shown. The crosspiece D is provided in its edge facing the ends E E with a longitudinal groove, F, the purpose of which will be presently described. At

their power ends the clamping-levers C C are provided with an eye, G, the eye G of one of the levers, C', being provided with screwthreads H.

I designates a rod or shaft, which has a bearing in the smooth eye Grof the lever G, while its other end portion, J, is screw-threaded and works through the screw-threaded eye G of the lever O. On the rod I, between the two levers, is arranged a handle, K, by which the rod can be turned. By turning the rod I in one direction its screwthreaded end will, as it works through the screw-threaded eye of the lever C', draw the latter inwardly, so as to throw its bifurcated inturned end outwardly, when the end of the saw-blade can be placed between the bifurcated ends of the levers and have its edge inserted into the groove in the cross-piece. The rod I has now only to be turned in the opposite direction, when the bifurcated ends of thev levers are brought together and securely clamp the saw.

With this handle one is enabled to crosscut or rip, and by a simple turn of the rod I the saw can be separated from the handle in a moment.,

When it is desired to use both hands, as in sawing large and heavy timber, an auxiliary handle may be provided. This handle consists of a rod, O, having a screw-threaded recess, P, in its end, by which it can be screwed on the end J of the rod I.

We claim as our invention- 1. As an improvement in saw-handles, the combination of a pair of clamping-levers having inturned bifurcated clamping ends, a connecting cross-piece on the ends of which the said levers are fulcrumed, having a grooved edge, an operating-rod arranged at the power ends of the levers, and having a bearing in one lever and a screw-threaded portion working through a screw-threaded eyein the other lever, and a handle portion arranged on the said rod between the levers, as set forth.

2. As an improvement in saw-handles, the combination of a pair of clamping-levers, an operating-rod arrangedy at the power ends of the levers, and having a bearing in one of the levers and a screw-threaded end portion work-V ing through a screw-threaded eye in the other lever, a handle portion arranged on the said rod between the levers, and an auxiliary rod screwed on the projecting screw-threaded end of the operating-rod, as set forth.

ln testimony that we claim the foregoing as our own we have hereto affixed our signa-- tures in presence of two witnesses.
